2. Strain gauge - Wikipedia

   en.wikipedia.org/wiki/Strain_gauge

   An unmounted resistive foil strain gauge. A strain gauge takes advantage of the physical property of electrical conductance and its dependence on the conductor's geometry. . When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, which increases its electrical resistance end-to-

3. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   These types of electronic pressure sensors generally use a force collector (such a diaphragm, piston, Bourdon tube, or bellows) to measure strain (or deflection) due to applied force over an area (pressure). Piezoresistive strain gauge: Uses the piezoresistive effect of bonded or formed strain gauges to detect strain due to an applied pressure ...

4. Load cell - Wikipedia

   en.wikipedia.org/wiki/Load_cell

   A strain gauge sensor measures the deformation of the elastic element, and the output of the sensor is converted by an electronic circuit to a signal that represents the load. Capacitive strain gauges measure the deformation of the elastic material using the change in capacitance of two plates as the plates move closer to each other.

5. Gauge (instrument) - Wikipedia

   en.wikipedia.org/wiki/Gauge_(instrument)

   Strain gauge: a device used to measure the strain of an object. Thread pitch gauge, also called a threading gauge, pitch gauge, or screw gauge a device used to measure the pitch or lead of screw threads. Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on.

6. Gauge factor - Wikipedia

   en.wikipedia.org/wiki/Gauge_factor

   Gauge factor (GF) or strain factor of a strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. The gauge factor is defined as: [ 1 ] G F = Δ R / R Δ L / L = Δ R / R ε = 1 + 2 ν + Δ ρ / ρ ε {\displaystyle GF={\frac {\Delta R/R}{\Delta L/L}}={\frac {\Delta R/R}{\varepsilon }}=1+2\nu +{\frac ...

7. Creep-testing machine - Wikipedia

   en.wikipedia.org/wiki/Creep-testing_machine

   Load platform or load hanger is where the object will endure pressure at a constant rate. [citation needed] Grips hold the material in a certain position. Position is important because if the alignment is off, the machine will deliver inaccurate creep readings. [citation needed] Dial Gauge is used to measure the strain. It is the object that ...
